ICING-MACHINE.

, Be'it known that I, ERNEST L. Sons, a citizen of theUnited States. of America residin at Pitt'sburg, inthe'count'yof Allegheny an State of Penns lvania, have invented certain new and usefu Improvements in Icing-Machines, of which the following is a specification, reference being had thereinto the acwith icing I com an 'ng drawin s.

s inventlon re ates to certain new and useful improvements in icing-machines, and

more. ;pa rticularly" to'that type of machine wherein a plurality of cakes can be coated as jelly or the like. v The primary object of this invention is to provide a machine by means of whichicing 'or other coating material may be a plied to 'cakes iin' quick succession and'wit perfect uniformity of thickness, whereby it will be possible to coat large quantities of cakes in a comparatively short period of time. I

I Anotherjobject of this invention -is to PTO? vide a novel form of machine in which a'plu- 'rality, of" cakes can be rapidly coated, novel means being provided whereb "each cake can befindependentl adj'uste during the coatlng operation'an then'conveyed to suitable receptacles adapted to contain the same.

The machine as constructed by me em- "bodies certain novel'features of construction 'whichlheretofore,to the best of my knowledge", have never been embodied in a machine of this type. 5 It is afwell-known factthat in. the manufacture *of cakes the thickness of cakes vary, and as the same are ve brittle it is necessary that the same be hand ed carefully." 'Heretofore in machines of this type "the variable thicknessof cakesvhas not been tflglarge u'antity ofcakes havebeen destroyed uring t e ic or coating process theirvariablc ii takenintoconsideration, and on this account p owing to t cknes'ses. I have provided v a novel self-adjustment for'each and every.

cake being] handled in my improved machine.

I 'h'ave also embodied novel means for'coating vcakesof various designs, novel means for roducing corrugatedor; like designed suracesupon the coated cakes, novel means for automatically feeding a plurality of cakes to the coatm mechanism of'my improved ma- 4 chine, an varions .:othernovel mechanisms I Specification of Letters Iatent. 7

deem it'necessary to illustrate these mech- IOC The machine as constructed" prises two skeleton frames 1 and 2, which are braced by suitable tie rods or bolts 3. Each frame consists of upper side rails 4, intermediate rails 5, and lower side rails 6. 5 Between the side frames 1 and 2 are mounted rollers 7 8 9 and a guide 10. These rollers, together with the guide 10, carry an apron or endless belt 11. The end of the roller 8 extends outside of the side frame 2 and is provided with a conventional form of box-ratchet 12. The apron-guide 10 is adjustably mounted in the side frames by formlng a slot 14 in each one of the upper rails 4, in which are mounted blocks 15 15. These 1 blocks are ad'usted in the slots 14 14 by screws 16, an each block carries a depending curved arm 17, which sup orts the apronguide 10. By means of the a justable apronguide the tension of the apron can be regulated.

Between the intermediate rails 5 5 of the I machine and at the forward end thereof are mounted rollers 18 and 19, the roller 19 being mounted between blocks 20, which are slidably mounted in slots 21, formed in the intermediate rails 5, and these blocks are adjusted by screws 22. The roller 18 protrudes through the side frame 2 and is provided with a box-ratchet 23, similar to the box-ratchet 12 heretofore mentioned. Over the rollers 18 and 19 travels an endless belt or apron 24, which is adapted to carry one or more receptacles 25, such as pans, which are ordinari used in connection with this type of machine.

Supported by the upper rails 4 4 is a platform 26, mounted on depending legs 27. The upper face of the platform is formed concave, as indicated at 28, and the sides of said platform are provided with substantially oval-shaped frames 29, between which is journaled an axle 30, upon which is suspended by arms 31 an icing receptacle or hopper. The icing-receptacle 32 has its bottom formed upon an arc corresponding to the concavity of the platform 26, and this receptacle is partitioned off into a number of compartments 33. The one side of the receptacle is cut away, as indicated at 34, whereby a surface-producing attachment can besecured thereto, the object of which will be hereinafter more fully described. These surface-producing attachments are illustrated in Figs. 11 to 13 of the drawings, and each attachment consists of a construction being employed whereby when plate 35, which is secured to the receptacle be iced or otherwise coated. The die 37 is provided adjacent to each aperture with a retainer 39, these retainers corresponding to the shape of the apertures 38, with the wee tion that they are mounted upon the one si e of the apertures, and in this instance, where the apertures are circular, the retainers are semicircular. The retainers are preferably secured to the die by Hanging the edges of the same and securing them upon the under face of the die by screws 40.

The reference-numeral 41 designates a receptacle which is mounted at the rear end of the machine upon the up er rails 4 4, and this receptacle is adapte to contain the cakes, that are to be iced or coated. The receptacle 41 isprovided with compartments correspondin to the number of compartments forme in the icing-receptacle 32.

To feed the cakes from the receptacle 41 to the icing mechanism of the machine I have provided a novel form of feeding mechanism, which will now be described.

Mounted upon the apron 11 is a plate 43. The top surface of said plate has an inclined portion 44. The forward edge of the plate is provided with a plurality of wedge-shaped grooves 45, in w 'ch are secured substantially wedge-shaped blocks 46, carryin retainers 47 One of these retainers is i lustrated in Fig. 3 of the drawings and comprises a substantially semicircular piece of metal or like material, which is of a greater de th intermediate of its ends than at its en s, this [00 the retainers enga e a cake they will hold and guide the same durin the forward movement of the plate 43. To carry the plate for- I wardly upon the apron, I have ivotally connected to the ends of the plate ars 48, which are pivotally connected to rods 49. These rods are ivoted u on a shaft 50, that is mounted etween the lower rails 6 at the rear end of the machine. Each rod is provided with a turnbuckle 51, whereby the rod may be adjusted. The shaft 50 is adapted to oscillate or rock, and to impart such movement to the same I have provided the shaft with a sl tted arm 51, to which is adj ustably connected a rod 52, that is connected to an eccentric 53, mounted u on the main driveshaft 54. This drive-s aft is journaled between the lower rails 6 6 at the rear end of the machine.

The reference numeral 55 designates a no substantially heartshaped grooved cam which is mounted upon the shaft 54, and operatin in the groove of the cam is a pin 56, carrie by the rod 57, that is adjustab y connected to an arm 58. The arm 58 is carried 1 25 by a shaft 59, journaled between the lower rails 6 6 of the machine. The one end of the shaft protrudes through the side frame 2 and is provided with a crank-arm 60 which is pivotally connected to an upwardly-extend- 13 cated at 62, toa crank-arm 63, carried by the in'grod' 61, that is connected, as indioneend of the. shaft of the axle 30.

The end of the shaft 54 which protrudes through theside frame .2 is provided with an eccentric 64, to which is connected a rod65,

that is adjustably oonnected to a rocking arm 66 ,:carried by the upper rail 4 of the side frame 2. vThe box ratchets 12 and 23 are adjustably connected to the rockingarm 66 by rods 67vand 68. I

"It will be observed by referring to Fig. 1 of 4 the drawings that the platform 26 is elevated above the apron 11, and in order that the Sm y e properly iced or. coated it ecessary that this apron be elev t the cakes are to be iced or coated. Itis f so necessary that after the icin been applied tothe cakes the cakes be re-' moved from the dies with considerable rapidity to assure a perfect surface of icing or coating being depositedupon the cakes, To accomplish this, I'have provided novel means for raising the apronv 11 and for permitting each cake to adjust itself to' the die through which the icing or coating1 is deposited upon the cake. To this end I ave employed flat s rings 69, which are connected to a bar'70,

t at is supported from the under face of the top rails 4. These springs lie under the apron,

- and the s rings are further supported by a bar 71,- t at rests upon substantially camshaped wheels 72. These wheels are of a articular formation, which will be resently lescribed, and they are mounts upon a shaft 7 3 journaled in the adjustable arms 74, carried by the top rails 4 of the machine.

. Each of the wheels 72 is rovided with a flat surface 75, which is pre erably formed ata radius to the axis of said Wheels. The shaft 1 7 3 is revolved by providingthe same with a sprocket-wheel 7 6, over which travels a chain 77 that also passes over a sprocket whe'el 78, carried by a shaft 79, journaled between de-,

- pending lugs carried by the top rails 4 4. The

shaft 79 is revolved by a belt 80, which trav-' els over pulleys- 81 and 82, carried by the 1 shafts 79 and-83, the last-named shaft 83 being journaled between the lower rails 6 6 of the machine. The shaftf83ealso carriesa 'SPI'OOkGtr'WhGBl 84, over whichla' chain, 8.5

be used for imparting arotary motion to the shaft 54 to place, the machine inoperation.

Operation; We will assume that the shaft .54 is rotatingand that the-aprons or endless belts 11 and 24 are being spasmodically moved by the box ratcliets-23 and 12, mo-

I a tionbeing' imparted to these ratchets through .the' medium ofzthe rods 65, 67 :me 68,'rocki'ng arms 66, and eccentric 64. It is therefore or coating has obvious that. when cakes are deposited upon the apron 11 they will be gradually carried to the forward end of themachine and deposlted into the receptacles or pans 25, which are moved spasmodically, whereby the cakes, will be deposited in rows in the pans. The cakes are placed in the rece tacle 41 one upon the other, andtheyare hel in this receptacle by the plate 43.-' This plate is reciprocated upon the a ron 1 1 through the medium of the ,bars 48, a justable rods 49, oscillatingshaft 50, and eccentric .53. When the plate 43 is moved forward, the cakes are retained in the receptacle '41 by the top surface of the plate, and when the front edge'of the plate recedes to a osition beneath the receptacle the cakes whic have been resting upon the top surface are carried by'jthe incline 44 and deposited in the retain'ers'47 carried by the front edge-of the plate 43. The distance the plate 43 travels 1s re ulated through the medium of the turnbuckle 51 and the adjustment of the rod 52 at the oscillatin "arm 51. The forward movement of the-p ate is limited by the de- %ending retainers 39, carried by the die37.

uring the forward movement of the plate 43 the apron 11 is being gradually elevated through the medium of the shaft 83, which is revolved by a sprocket-chain and s rocketwheel 85,belt' 80, pulleys 81, and s aft 73, which latter carries the wheels '72. These wheels are substantially cam-shaped and are adapted to elevate the'bar 71, carrying the fiat springs .69. -As these springs beara ainst the under face of the apron it is raise into close proximity to the dies, the gradual ele- I 55, the rocking'arm 58, rod 61', and s aft 36, and as the receptacle is suspended from this shaft it will be moved'across' the die 37, back again, and then held stationary fora short period of time while the apron 11' is-receding and the plate'43f isfret'urn'ing' to receive other Cakes from therece 'tacle 41.' I have provided the substantiallycam-shaped wheel 72 with the-'flat surface 75, whereby after the icing or other coating'has been ap lied to the cake's'a sudden and-positive wit drawal of the apron 11 from the die '37 is accomplished,

this occasionedbythe' bar '71, carrying the springs :69, dropp ng from the maximumrams of the wheelj'72 to the minimum radius .or coating receptacle 32 Y thereof. The forward movement of the icing receptacle 32 deposits athin layer of icin or other coating '11 on the surface of the ca es exposed throug lithe openings of the die, and the return movement of the receptacle places a serrated or corrugated surface u on the icing or other coating. To accomplish I have provided the surface-producing attachments illustrated in Figs. 11 to 13, inelusive, which consist of the plate 35, having an ed esuitable for producing the surface 11euired. By attaching one of these plates to t 'e side of the receptacle I can produce various surfaces upon the icing or other coating that has been previously deposited upon the cakes by the'forward movement of the icingreceptacle. During the operation of the machine should any of the cakes vary in thickness the cakes will adjust themselves to the die-openings through the medium of the springs 69, the forward ends of which permit cakes of greater thicknesses than the other cakes receding slightly, whereby the same amount of icing or other coating will be placed upon each cake being iced. To perployed receptacle sus mit of cakes being coated of thicknesses that vary more than one-eighth of an inch, I have made the arms 74 ad ustable, whereby the elevation of the shaft 73 can be changed, whereby a cake an inch in thickness can be coated as perfectly as a cake one-eighth of an inch in thickness. The slight adjustment of the arm 7 4 willnot interfere or re uire an adjustment of the chain 77, as this 0 ain can be made suiiiciently loose upon the sprocketwheels to permit of the adjustment of 'the shaft 73.

To accomplish the intermittent movement described by the receptacle 32, I have cmthe heart-shaped cam but I do not care to limit myself to this mechanical device for accom lishing this movement, nor do Icare to confine myself to the other mechanical devices employed to o erate the machine and produce the spasmo ic oscillating and reciprocatory movements used in connection with my improved machine.

It will be understood that while I have herein shown the machine as being constructed capable of coating five cakes at a time the size of the machine can be increased to produce a greater quantity of coated cakes.
